If it's not due to a different width or offset spec rim, then it's gotta be something to do with
YOUR fenders or the tires themselves, as there's quite a few 2020+ Spyders out there successfully running those same size/make tires. So hopefully you can confirm the rim spec detail with PPA & resolve any issues/concerns there.

hyea:
When it comes to the rest, then as has been suggested already, it could be that the fenders haven't been mounted quite the same way/properly; or maybe it's the wrong tire/too high in the pressure department?? Regardless, it really shouldn't take too much in the way of investigation to find out what it is. Did you check the fenders & fender brackets to ensure they're all mounted properly &/or that it's not just the protrusion of 'raised hex heads' on the fender fitting screws that's doing the touching?? Many have found the fender fitting screws with her head that protrudes into that 'wheel well' area, sometimes by as much as 10-15 mm juuust touch the tire tread &/or inner sidewall on rotation.... so replacing those OEM screws with pan-head screws of the same type/length will usually resolve that particular issue.

And what about checking to make sure that the tires you got actually are /60 profile tires, & not 65/'s?? As BR mentioned, "Stranger thangs have happened!"

OR, you say the tire pressure in the Vredesteins is 17 psi; did you confirm that
yourself with
your tire pressure gauge? :dontknow: Unless you did it yourself, many tire fitters will use 40+ psi to seat the beads, only to then 'forget' to lower the pressure to the correct/specified by user pressure, and what you're describing is only ONE of the potential adverse results
that can bring about! :banghead:
I'd suggest there's a tad more investigation required before you start panicking &/or scrambling to buy another set of tires - or rims.... not so sure about the rims tho, as any investigation there might juuust reveal that the new rims aren't really 'identical' to the OEM Rims when it comes to 'Fit'...

But I'd sincerely hope that a little more investigation will reveal some fairly simple reason you this being an issue on your Spyder Troop, as many others have fitted the same tires without this problem. Here's hoping you can sort it without too much trouble! Good Luck! :cheers:
